DS1877 SFP控制器，提供雙Rx接口
 
The DS1877 controls and monitors all functions for SFF, SFP, and SFP+ modules including all SFF-8472 functionality. The device supports all LOS functions for two receivers, and continually monitors for LOS of either channel. Four ADC channels monitor VCC, temperature, and two differential external monitor inputs that can be used to meet all monitoring requirements. Two digital-to-analog converter (DAC) outputs with temperature-indexed lookup tables (LUTs) are available for additional monitoring and control functionality.
